Patent DE-3724900-A1 (DE)
Inventor: STELTENKAMP ROBERT JOHN
IPC: A01N37/18
Filed: 1987-07-28
Abstract: N-lower alkyl neoalkanamides of 1 to 4 carbon atoms in the lower alkyl thereof, and of 5 to 14 carbon atoms in the neoalkanoyl group, e.g. N-methyl- and N-ethyl neodecanamides, are new compounds which have pestrepellent properties, being especially effective against insects such as cockroaches. They may be applied directly to surfaces to be treated or they may be incorporated in detergent compositions, such as laundry detergents, floor and wall cleaners, rug cleaners and shampoos, hair shampoos, and liquid and bar soaps, and have been found to be sufficiently substantive to the substrate being washed so as to impart insect repelling properties to it. In addition to insect repelling uses, the N-lower alkyl neoalkanamides are also useful components of perfumes.

Patent DE-3822994-A1 (DE)
Inventor: ZABLER ERICH DIPL ING DR
IPC: G01F23/296
Filed: 1988-07-07
Abstract: In a level indicator (12), in particular for fuel tanks (10) of motor vehicles, a transmitter (13) induces flexional waves (17) in a sonic conductor (11). The level(h)-dependent feedback on the sonic field dimensions in the sonic conductor (11) at the transmitter (13) or in its vicinity (sonic immittance) is used to determine measurement values. For that purpose, the changes in cross impedance are evaluated. A linear measurement gradient is obtained that can be clearly associated with a level (h) within a half-angle of the change in phase angle.

Title: Analysis system
Inventor: FRACKLETON JOHN J
IPC: G01N33/49
Filed: 1989-05-19
Abstract: An analysis system has a metal-body construction which defines an analysis chamber whose metal surface is essentially chemically inert.

Inventor: GROSSMANN HORST DIPL CHEM DR
IPC: C01G19/08
Filed: 1989-09-04
Abstract: In this process, high-purity tin tetrachloride is produced from metallic tin and chlorine in a single reaction chamber. This is done by dissolving gaseous or liquid chlorine in circulating liquid tin tetrachloride. This solution is then passed into the bottom of a vertical tubular reactor containing loosely packed granulated tin. About half-way up the granulated-tin column, the tin tetrachloride is taken out of the reactor in order to increase the chlorine concentration and recycle it into the reactor. At the same time, the heat of reaction contained in the liquid tin tetrachloride can be extracted using a heat exchanger.

Patent DE-4013570-A1 (DE)
Title: Ascertaining earth's gravitational field from on-board aircraft - continuously measuring acceleration and integrating resultant signal twice to derive signal resembling height
Inventor: SCHAENZER GUNTHER PROF DR ING
IPC: G01V7/16
Filed: 1990-04-27
Abstract: The height-resembling signal derived from integrating the acceleration signal twice is compared with the height signal from a permanent separate height measurer. The difference signal is used as a direct measure for the change of the earth's gravitation vector. By calibrating the superimposed system errors arising chiefly from the instrumentation employed, errors are eliminated. As well as the interference acceleration related to flight path conditions, the centripetal and Coriolis accelerations are compensated. The compensation is achieved by a series circuit of sensor dynamic and model providing delays of the complete system. The path shift between the original signal and display deriving from these delays is completely eliminated by off-line post-processing.
